Benefits of technology
This patent describes an aspiration hopper assembly that is designed to disperse and collect materials. It includes a covered hopper with angled side walls and an open bottom. It also includes an inlet, a diverter vane, an adjustable product depth plate, and a slidably adjustable product wave plate. The assembly is attached to an air tube housing that includes an air tube with a cut-out section. The cut-out section is connected to an air pick-up zone of the housing. The assembly also includes an adjustable velocity plate. The technical effects of this innovation include improved dispersion of materials, increased control over product depth, and better air pick-up.
Problems solved by technology
While useful, the velocity of product flow and air flow are not adjustable and therefore current devices are not adaptable to different product characteristics.
Furthermore, current devices do not provide a visual means to adjust product flow and airflow during operation.

Embodiment Construction
[0012]Referring to the Figures, an aspiration hopper 10 has a closed top 12, end walls 14, and side walls 16 that are angled inwardly from the top 12 to an open or closed bottom 18. The angle of the side walls 16 in relation to a horizontal plane is predetermined based upon the product.
[0013]Product will enter the aspiration hopper above side wall 16 on the same side as the diverter vane 20. Disposed within the hopper 10 and connected to the side wall 16 is a diverter vane 20. The diverter vane 20 is positioned within the hopper 10 to disperse product across the width of the hopper 10. Attached to the end walls 14 is an adjustable product depth plate 22. The product depth plate 22 is adjusted or moved within a slot 23 based upon the product flowability to further disperse product across the hopper 10 width. By changing the direction of product travel, the rate of product flow is slowed. An adjustable product wave plate 24 slidable within slot 25, preferably made of a corrugated mate...

An aspiration hopper assembly having a diverter vane, an adjustable depth plate, and a slidable product wave plate disposed within and connected to an aspiration hopper. Below the aspiration hopper is an air tube housing having an air tube with a cut-out section, an air pick-up chamber, and an adjustable velocity plate. Sight windows provide a means for visual inspection to monitor performance when making the adjustments for optimal results. The purpose of the aspiration hopper assembly is to allow good product to pass through the aspiration hopper in order to remove foreign material that is the similar size and lighter in density from good product.
Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 62 / 577,200 filed Oct. 26, 2017, the contents of this application is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]This invention is directed to an aspiration hopper assembly and more particularly to an aspiration hopper assembly where the airflow is adjusted based upon different product characteristics.[0003]Aspiration hoppers are known in the art for removing foreign material known as air liftings from product. One solution for separating air liftings by density has been through the use of air. While useful, the velocity of product flow and air flow are not adjustable and therefore current devices are not adaptable to different product characteristics. Furthermore, current devices do not provide a visual means to adjust product flow and airflow during operation.[0004]An objective of the present invention is to provide an aspiration ...
